SPECIFICATION forming part of Letters Patent No. 442,739, dated December 16, 1890.

Application filed March 27, 1890. Serial No. 345,619. (No model.) Patented in England April 2, 1889, No. 5,644-

To all whom it may concern.

Beit-known thatLTHoMAsSIDNnYSHoULER, a subject of the Queen of England, residing at Leicester, in England, have invented certain new and useful Improvements in or Relating to Turns or Fasteners for Cupboard- Doors and the Like, (for which I have obtained English Patent No. 5,6 dated April 21889,) of which the following is a specification.

This invention relates to improvements in fastenings for cupboard-doors and the like; and it consists in certain novel details of construction, combinations, and arrangements of of parts, to be hereinafter described, and pointed out particularly in the claim at the end of this specification.

The invention will be understood from the following description in reference to the accompanying drawings, inwhich Figure 1 is a representation in vertical section of my improved cupboard catch applied to cupboard-doors, the latter being closed and the catch locked. Fig. 2 is a sectional elevation on the line Y Z of Fig. 1. Fig. 3 is a horizontal section showing the lefthand door held in position by the rabbet on the right-hand door. Fig. at is-a front elevation of the catch or fastener. Figs. 5 and 6 are modifications in perspective.

On the spindle A of an ordinary door-knob I mount a plate B, with a square hole or otherwise, so as to turn with the spindle. This plate is provided at its 'upper end with a ton ue B, beveled at B to facilitate its engagement with the catch-plate C, fixed on the front edge of the cupboard-shelf 0', when the door is closed. The plate 0 may be fixed to any other desired part of the cupboard.

The plate B is movable on and secured to the inside of the cupboard-door by a screw D or equivalent, carrying also a spring E E, the uprightarms of which bear against the sides of a slot B in the plate B. The lower curved end of the spring E E fits into a recess in the distance-plate F, Fig. 2, and the arm E of the said spring bears also against the inside edge of a slot in the distance-plate F, so as to cause the plate B to resume its vertical or normal position after it has been moved laterally, as indicated by the arrow in Fig. 2.

The distance-plate F is loosely fixed on the spindle between the door and plate B, so that the tongue B stands sufficiently proud of the door to enter a recess 0 in the edge of the cupboard-shelf O. The plates B and F are kept in position on the spindle A by a nut A. The improved catch, as described, is fixed on the right-hand door or the door G, with the overlapping flange or rabbet G, Fig. 3, so that when the doors are closed and the tongue B of the plate B engages the plate 0 the left-hand door II will be held fast by the rabbet G. When the door to which the catch is fixed is closed, the beveled side B of the tongue B will come into contact with the beveled edge of the plate 0 and will be moved laterally thereby, the spring E causing the tongue B immediately it is clear of the edge 0 01 the plate 0 to resume its normal or vertical position and engage with the back of the plate 0, as shown in Fig. 2, and the doors will be locked in position. Byturning the knob A the tongue 13 may be disengaged from the plate 0 and the door can be opened.

In the modification shown in Fig. 5 a lever J and distance-plate J are mounted on the spindle A, and the end J 2 of the said lever is beveled, so that on the door being closed it comes into contact with the beveled lower end of the plate K, fixed to the cupboardshelf K, preferably by screws, and will be depressed and pass under the plate K, and, owing to the lever J and distance-plate J being fixed out of their center, the parts to the right of the spindle A in Fig. 5 are sufficiently heavy to cause the opposite end to rise after being depressed and the end J 2 of the lever J to engage with the plate K, as shown.

- In the modification shown in Fig. 6 the lever Lis bent at its forward end, so as to avoid the necessity of a distance-plate, as shown in Fig. 5, and is provided with a slot L, workingon a pin L on the inside of the cupboard-door to restrict the movement of the lever L.

The contrivances or devices hereinbefore described can be employedwith single doors when desirable.

ICO

certained the nature of my said invention and plate to return the former to normal position, substantially as described.

In testimony whereof I have hereto set my hand in the presence of two subscribing Wit- I5 nesscs.
